Estra...a life saving solution Glazed louvred smoke ventilator The Estra is the solution where an aesthetically louvred ventilator is required for either low level inlet or high level smoke ventilation, typically in glass façades. The Estra extracts large volumes of smoke, utilizing the buoyancy of hot gases in the rising plume. Natural day-to-day ventilation is driven by pressure differences to move fresh air through the building. Pressure differences are caused by wind or the buoyancy effect created by temperature differences commonly known as the stack effect. The Estra is available with a wide variety of louvre types including single or double glazed, polycarbonate and aluminium.
